Firefox hangs with some websites

more options

Firefox hangs scrolling the newest models on Printables (https://www.printables.com/model?o=newest). The problems starts occuring several "pages" down the endless list. While scrolling I open interesting models with shift+click. At first opening models starts taking several seconds and some time later I can't scroll further down. Firefox shows a notification: "This page slows down Firefox".

YouTube videos won't start playing (again after opening with shift+click). Sometimes I can get them to start by clicking several points on the timeline and sliding back to the beginning. At first everything is fine, but after several videos the problem starts.

Google Chrome doesn't show this behaviour, but I would rather stay with Firefox.

Check for malware

If clearing your cookies and cache did not enable you to load the websites that did not work in Firefox, you should check your computer for malware.
